Our company***s dynamic balance electric control valve electric control valve is different from the traditional new generation product, is a dynamic equilibrium with the electric control integration products. As shown below, the AC system load fluctuations larger, when the system pressure changes, the dynamic balance of electric control valve the pressure difference of the two ends (P1-P3) changes;
(1), when the inlet pressure P1 increases, (P1-P2) increased, while the electric valve spool upward movement, the P1, P2 between the opening degree reduced, spool pressure P2 decreases; when the inlet pressure decreased P1,
(P1-P2)Reduced, then electric valve spool downward movement, the P1, P2 between the opening degree increases, the spool pressure increased P2. Therefore, no matter what changes the pressure, regulating the electric valve spool, P2, P3 between the pressure remains constant. Therefore, the pneumatic valve and strong anti-interference ability, has the functions of dynamic equilibrium;
